To all whom t may concern:

Be it known that I, DANIEL G. EDWARDS, a citizen of the United States,and residing at Atlanta, county of Fulton, State of Georgia, haveinvented certain new and useful Improvements in Cable-Hangers, of whichthe following is a specification, reference being had therein to theaccompanying drawmg.

My invention relates to cable hangers of that type commonly used for thesuspension of telephone conductor cables upon steel or other spancables. It is however not limited to such use, being capable ofusewherever any cable is to be suspended from a relatively iiXed support,such for instance as in the so called catenary suspension systems ofelectric railways. In such systems the trolley is supported from acatenary cable by hangers of various lengths so that the trolleyoccupies a substantially straight line free from sags or otherdisturbing irregularities.

The objects of my invention are manifold. I have aimed to produce acable hanger which in the first place did not wear, cut or crystallizethe lead sheath of the telephone cable which in the second placepermitted the cable to be freely drawn therethrough, which in the thirdplace could be readily and strongly secured upon the suspension cableand which in the fourth place could be economically manufactured andmarketed. As will be seen upon an understanding of my invention, I haveattained all of these objects by utilizing a construction in the mainheretofore unknown to the art. Most of the devices heretofore on themarkethave been defective along one or more of the lines set forth. l

In the accompanying drawings I show the best forms of my invention nowknown to me, but I Adesire to have it understood that my invention maybe given other forms ing in any wise from its generic spirit, and in theclaims annexed 'hereto I intend to cover such modifications.

Of the drawings Figure 1 shows the prin` cipal form of my invention inside elevation and partial section,

Fig. 2 shows a blank sheet metal from which this form of the device ismade,

Fig. 3 shows a modified form of any similar lines,

Fig. 4 is anend elevation of asecond modification,

by those skilled in the art without depart` Fig; 5 is a side view of thesame with the top in section,

Figs. 6 and 7 are partial side and end elevations of a third form, and

Fig. 8 is a side elevation on a reduced scale of a fourth form.

Fig. 9 is al plan view of a blank from which theadditional modificationshown in Fig. 10 is formed, and

Fig. 11 is a plan view of the blank from which the still furthermodification of Fig. 12 is formed.

Referring to Figs. 1 and 2, the band of metal of Fig. 2 is punched froma strip or sheet by a-suitable machine. It is then formed up by hand orother suitable machine into the loop 10 of Fig. 1. The loop y is of asubstantial circular shape (as in the form of Figs. 4 and 5), and itsprincipal bearing surface 11 at the bottom is formed of cylindricalshape and of substantial width (or length) of cylindrical surface. Bysubstantial width I mean a width so great that there will not beappreciable wearing, cutting, or crystallizingaction on account ofvibration and friction, rarely entirely Vabsent and in windy weathervery great in degree. The type of the cable hangers now in use make useof a sharply curved bearing surface at the point 11, and the wear uponthe cable sheath is considerable, resulting in a period of months in asmall opening in the lead sheath whereupon the cable conductors aresubject to weather conditions and troublesome cross and ground circuitsresult. This cannot occur in the hanger 'of my invention. Preferably thewidth of the bearing surface quarter inch to two inches the size andweight of the cable to be sup ported. The outer edges of the surface 11are curved outwardly on an arc of Small radius to ease the cable when itis being drawn through, and to prevent any cutting or scarring of thesheath or insulation thereof. l i

The upper ends 12 of the loop Fig. 1 are formed symmetrically with thebody 10 thereof, but of less width. When the blank 3 is punched orformed, temporarycomplemental fastening means is formed at correspending points on the two ends 12, these fastening means in the"`present embodiment consisting of the lip 13 punched out of one end --12and adapted to project through a slot 14 punched in the other endthereof.

depending upon When the .body 10 of the loop is formed up into circularshape, the ends 12 are bent toward each other and temporarily fastenedin contiguity by projecting the lip 13 through the slot 14 and springingor bending it over. Thereafter` the two ends 12 are integrally united bygalvanizing, soldering, brazing'or the like, or by means of any otherpermanent fastening means of great strength. Their extremities are bentover to form a hook 15 by means of which the loop may be hung from thesuspension wire as indicated. In this form of my invention, the ends 12are permanently united together throughout their lengths, whereby a hook15 of very great strength is had. Thus while the punching of Fig. 3 maybe from very thin metal, the body of the loop 10 is braced by theoutwardly turned edges, and the hook being formed of a double thicknessis'of more than ample strength. At the same time the material andproportions are such that the hook may be readily bent to form an eyesurrounding the suspension wire, or adjusted to suspension wires ofvarious sizes as desired.

The modification of my invention shown in Fig. 3 diers from that shownin Figs. 1 and 2 principally in the fact that but one end 12 is bent toform the hoolr 15 instead of bothy ends thereof as in Figs. 1 and 2.

l'Ihe form of Figs. l and 5 differs from the forms of Figs. 1 and 2 inthat while both ends are bent over to constitute the hook 15, they arebent over from opposite directions, and are not temporarily orpermanently fastened together before being placed upon the suspensionwire, the portions of the ends 12 adjoining the body 10 of the loop,being spaced apart a distance approximately equal to the diameter of thesuspension cable. If desired of course these ends might be fastenedtogether near the body 10, and the ends left free to be over-lapped overthe suspension cable and over each other from opposite directions.Thereafter the lapped ends might be permanently soldered or otherwisefastened together.

Figs. 6 and 7 show a form of my invention di'ering very considerablyfrom the preceding forms, in that the ends 12 of the loop aredissymmetrically formed as respects the main body 10, one on each sideof the central plane thereof and of a width approximately equal toone-half the width of the body 10. These ends when lapped over thesuspension cable therefore independently engage the suspension cable,and are independently bent under the suspension cable from oppositedirections to form two eyelets as clearly shown in Fig. 6. Obviouslythese end portions do not over-lap each other, but instead rest upon thesuspension cable side by side. This form has the advantage thatregistering notches 16 may be formed on the adjacent edges of the ends12, and in such longitudinal position that when the ends are bent overto form the eyelets as shown in Fig. 6, the ends 12 may be forcedlaterally a small distance beneath the suspension cable and caused tointersect each other and lock together. This is clearly indicated inFig. 7. Thus while not interconnected above the suspension cable, thetwo ends 12 of the loop are interconnected below the suspension cablewith substantially the same increase in holding strength.

In the fourth modification ofV Fig. 8, instead of cutting the ends 12 ofreduced width, the entire band of metal is cut of the same width, andthe hooks 15 formed by bending the extremitiesy of the band toward eachother from opposite sides while the body portion 10 of the band is bentinto a spiral loop. Thus the ends 12 dodge each other and when placedupon the suspension cable engage it separately. As in the form of. Figs.6 and 7 the extremities of the ends 12 are bent over and under thesuspension cable to form eyelets,` and may be interconnected throughnotches as in the form of Figs. 6 and 7 Y In the principal forms of myinvention heretofore described, there will be noticed a very prominentfeature, to wit, the concave transverse form of that portion of the hook15 which engages the messenger cable. By reason of this concavity, thehook engages the top of the messenger cable Vby its edges, and it istherefore far less liable to slip along the cable and become displacedas the conductor cable is being drawn through, than are the old forms ofthese devices in which the tops of the hooks 15 were fiat or convex ontheir under sides.

In the form of Figs. 9 and 10 the blank is cut with the two end portions12 parallel but laterally 'displaced to positions in which they do notoverlap, as indicated by the dot and dash line connecting their adjacentedges, and the main body 10 interconnecting these end portions extendson a bias between them. The tops of hooks 15 are formed concave on theirunder sides as clearly illustrated.

The form of Figs. 11 and 12 is similar in general to the form of Figs. 2and 5 with the exception that the lateral margins taper toward eachother from the' center outwardly, whereby when "turned there are formededge flanges of progressively decreasing width from the bottom of thering to the top asclearly shownin Fig. 12. The concave hook 15 is alsoclearly shown in Fig. 12. Y

What I claim is: v Y

1. A cable hanger comprising a band of metal bent to form asubstantially closed loop with upwardly extending ends or pro jections,said loop adapted to receive and hold a cable and said ends beingeppositely bent to form overlapping hooks which when the hanger is inposition will rest upon the suspension or messenger wire one within theother with the ends on opposite sides ot' the wire, whereby the ends aresecured together and with the loop form a. closed ligure, independentmovement of the ends under suspension strains or swaying beingprevented.

EZ. A cable hanger comprising a band of metal bent to form a loopadapted to hold a conductor cable, and provided at its upper end with asupporting hook formed of strip metal and concaved on the under sideoit' its top whereby it engages the messenger cable by its oppositeedges as contradistinguished from its central portion.

3. A cable hanger for use with a messenger wire or cable comprising aband of stiii' metal formed into a closed cylindrical loop of greaterdiameter than the cable to'bc supported therein, the opposite edges ofthe band being turned over all around the loop to form a. narrowstiiiening liange, whereby theshape ofA the loop is preserved understrain and the cable permitted to ride freely therein on a broadcylindrical surface, while the ends of the band are extended radiallywith respect to the loop having a hook integrally formed upon them toengage the messenger wire, said hook being concaved or channeled on itsinner surface, whereby its weight and the weight of the cable will besupported upon its outer edges, and longitudinal sliding movement of themessenger wire will be reduced to a minimum.

Ll. A cable hanger comprising a band of meta, b Vnto a loop withoutwardly ef;- tending ls or projections, said loop adapted to receiveand hold a cable and said ends bent to form suspension hooks for theloop, the said hooks being concaved or channeled on their inner surfaeesto term edges for eni gagement with a si rt.

5. L cable hanger for use with a messenger wire or cable comprising aband of still' metal formed into a closed cylindrical loop of greaterdiameter than the cable to be supported therein, the opposite edges olthe band being turned over all around the loop to form a narrowstillfeningilange, whereby the shape oit the loop is preserved understrain and the cable permitted to ride freely therein on a broadcylindrical surface, while the ends of the band are extended radiallywith respect to the loop having a hook integrally formed upon each oithem to engage the messenger wire, said hooks having their open endsturned in opposite directions, and long enough to come below themessenger wire when in position, whereby said messenger wire is inclosedbetween two members of the band on each side, and lateral displacementthereotl is prevented by the weight of the loop and the weight of thecable.

In testimony whereof l aiiix my signature in presence of two witnesses.
